There is very little specific information available about the biology of the slender skimmer. Like all dragonflies, the slender skimmer starts its life as an aquatic larva or nymph, and passes through a series of developmental stages or ‘stadia’, and undergoes several moults as it grows (5).
The length of the larval stage varies between species, although it may range from a few weeks to several years. The larva emerges from its final moult having metamorphosed into an adult dragonfly with characteristic features such as wings and enlarged compound eyes (5). The wings of the newly emerged adult expand and harden rapidly, enabling flight soon after the final moult (5) (6).
After emergence, the adult dragonfly leaves the water and spends anything from a few days to several months feeding and maturing. It is in this maturation period where the dragonfly normally develops its full adult colour (5).
Although little is known specifically about reproduction in the slender skimmer, there is often fierce competition between male dragonflies for access to reproductive females. Females typically begin to lay eggs in water immediately after copulation, often guarded by the male. However, females of some dragonfly species can store live sperm in their body for a number of days (5).
The slender skimmer is renowned for feeding on other dragonfly species, including some species larger than itself (7).
